Science Experiments

Question: 7th grade science project?

I need to find an experiment for a project about vision problems and correction. I’m thinking about having people read off the eye chart, but I might get a low score on my project?! This experiment/activity needs to be able to have variables, a hypothesis & blahblahblah. you get it? okay thanks to whoever answers this question.
and btw I CANNOT FIND ANYTHING ONLINE!!
oh and also; i need to have an experiemnt which i can show to the class, not just the data.
i knoo tough! this project is worth 100 points!!

Answer: have a project about how people get glasses, kinds of eye problems(variables are sitting near tv sets make you have eye prob.)
